Unique family of halide perovskites displays surprising behaviors under hydrostatic pressures /  La famiglia unica di perovskiti agli alogenuri mostra comportamenti sorprendenti sotto pressioni idrostatiche Segnalato dal Dott. Giuseppe Cotellessa / Reported by Dr. Giuseppe Cotellessa Topological insulators are a novel quantum state of matter with important properties for various applications. Yalameha et al. investigate the topological phase of a class of halide perovskites, CsSnX 3  (X=I, Br, Cl), under hydrostatic pressures. CsSnX 3  materials are unique due to their breadth of remarkable properties, including their tunable bandgap, high optical absorption, broad adsorption spectrum, small carrier effective mass and high charge carrier mobility. The narrow band gap of these compounds makes them especially interesting for electronic, optoelectronic and photovoltaic applications. The authors used density functional theory calculations to study struct...

Eat Less, Live Longer /   Mangia di meno, vivi più a lungo Segnalato dal Dott. Giuseppe Cotellessa /  Reported by Dr. Giuseppe Cotellessa If you want to reduce levels of inflammation throughout your body, delay the onset of age-related diseases, and live longer--eat less food. That's the conclusion of a new study by scientists from the US and China that provides the most detailed report to date of the cellular effects of a calorie-restricted diet in rats. While the benefits of caloric restriction have long been known, the new results show how this restriction can protect against aging in cellular pathways, as detailed in Cell on February 27, 2020. "We already knew that calorie restriction increases life span, but now we've shown all the changes that occur at a single-cell level to cause that," says Juan Carlos Izpisua Belmonte, a senior author of the new paper, professor in Salk's Gene Expression Laboratory and holder of the Roger Guillemin Chair. ...

Treating Cancer – 5 Types of Immunotherapy /  Trattamento del cancro - 5 tipi di immunoterapia Segnalato dal Dott. Giuseppe Cotellessa /  Reported by Dr. Giuseppe Cotellessa   Numerous treatments are available to patients with cancer.  Several factors  including; the type and stage of a patient’s cancer, their general health, and preferences impact treatment options. Some available treatments harness the  immune system  – the body’s natural line of defense against infection and disease – to fight cancer. What is immunotherapy? Immunotherapy (also sometimes referred to as  immuno-oncology ) is a type of cancer treatment that exploits the body’s immune system to fight the disease. Some types of immunotherapy can be  preventive  (e.g. cancer vaccines) but the majority are  therapeutic . Immunotherapies help the immune system  recognize, attack and destroy  cancerous cells. This list explores the diffe...
